I've painted dozens of fantasy castles and architectural studies. People love them and these pictures always sold at conventions. My challenge was to keep it from being too repetitive. It could just be one interchangeable late medieval castle after another. So I would add interesting bits like a tiny dragon here or there, or some unusual colors, or in this case, the "faerie winds" which were represented by wispy drifts of mist. The mist was easily depicted by thinning out white paint so it was semi-transparent, something acrylic paint was very good at. No tiny dragons in this one though.
"Faerie Winds Castle" is acrylic on illustration board, 7" x 9", June 1996.
